HPA SERIES HIGH PRESSURE, BALL SEAL, SCREWED COUPLINGS
INTRODUCTION
Holmbury High Pressure Ball Seal Screwed Couplings can be connected and
disconnected even with a low residual hydraulic pressure in the line.
The screw connection mechanism eliminates Brinelling (indentation of the locking
balls into the retaining groove) and thus makes the couplings suitable for high
pressures and pressure pulse applications.
Two sizes are offered, 1/4" and 3/8" NPT.
FEATURES
- Compatible with all high pressure pump and cylinder manufacturers (Enerpac,
SPX, Larzep and Hi-force)
- Connection and disconnection can be performed even with low residual
hydraulic pressure in the line.
- Screw thread retaining mechanism eliminates Brinelling
APPLICATIONS
General industrial equipment
MATERIALS
Zinc plated carbon steel body material with nitrile seals and PTFE backing
ring. Other seal materials available on request.
TECHNICAL DETAILS
Maximum working pressure for both sizes of couplings is 700 bar. Working
temperature range with nitrile seals is -20C to +100C.
